Description
CATO manufactures 4-(2-Chloro-5-(trifluoromethyl)phenyl)pyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
4-(2-Chloro-5-(trifluoromethyl)phenyl)pyridine (CAS 4393-93-5) is a high-purity analytical reference standard with the molecular formula C12H7ClF3N and a molecular weight of 257.64 g/mol.
4-(2-Chloro-5-(trifluoromethyl)phenyl)pyridine (C12H7ClF3N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
